Pork Au Poivre

Slice tenderloin lengthwise, being careful not to cut through to other side. Split meat into one large, flat piece. Spread mustard over both sides of the meat and rub in pepper, pressing gently so it adheres well. Cut meat crosswise into 4 even portions. In large skillet, heat oil over medium flame. Put tenderloin in the pan and cook for about 10 minutes or until meat thermometer reads 155 degrees, turning once. Transfer meat to a plate and tent with foil to keep it warm. Add chicken broth and wine to pan and cook over medium-high heat, scraping up any bits that have stuck to the pan. Continue to cook for 8 to 10 minutes or until sauce is reduced to about ½ cup. Pour sauce over meat, season with salt, and serve.
